It would be very nice to see live feed back in the app to show your current tilt angle and degrees as well as where you have your trigger settings and noise settings at.  It would make setting up the advance tilt settings much easier instead of trial and error with games.  Being able to see how far to each direction you tilt the mouse would allow you to setup the trigger tilt angle.  Showing how much you are tilting the mouse inadvertently would allow you to set your noise level based off your personal movements and the different feet positions one can have.  Something like how PlayStation and Xbox have joystick calibrations what show where the sensors are reading the joysticks as you move them around and have at rest so you can set the dead zones.  I think this would be such a valuable tool to diagnose if you need to recalibrate or have a faulty gyro as well.
